摘　　要：基于模式匹配技术的迭代综合方法优化设计了94 GHz的TE11-HE11模式转换器.采用商用电磁仿真软件对设计的模式变换器的性能进行了验证,两者结果基本一致.在88～102 GHz的频带范围内,模式输出纯度超过98％,其中最大模式纯度为99.1％.设计的基于半径微扰的光滑壁圆波导结构的模式变换器结构简单,易于加工,同时避免了波纹模式变换器波纹间隔易发生击穿的弊端.A 94 GHz TE11-HE11 mode converter using an iterative synthesis method based on mode-matching technology is presented.The commercial electromagnetic simulation software is used to validate the design.The simulation results meet the requirements of design.The purity of output mode of the converter is over 98% at 88 GHz to 102 GHz,and the highest is 99.1%.The structure of smooth circular waveguide based on waveguide deformation is easy to process,avoiding the disadvantage that corrugated waveguide is easy to breakdown.
